Family vacations can help bond a family together and show kids the vastness of the world, Erin Stewart writes. - photo by Erin Stewart
Its that time of year again: Tulips are blooming, and kids cant sit still in class. Thats right: Spring!

Its also the time when moms and dads are looking ahead to summer vacation and wondering how theyre going to spend the time off. If youre like me, I would jam the whole summer full of trips if I had the time and money. I love going somewhere new and having dedicated family time away from the to-do list that haunts me at home. I even love the planning for the trip almost as much as the trip itself. Looking forward to the time away makes the excitement last longer than the actual vacation.

My husband, however, is a bit of a curmudgeon when it comes to family vacations. Hed be just as happy staying home, maybe getting wild and eating at a buffet and then letting the kids run through the sprinklers all summer. He hates the idea of shelling out money for a trip that is over in a week, leaving you with only a smaller bank account and a bunch of laundry.

So, if youre in my boat and you have a significant other that gives the old family vacation a big, unenthusiastic thumbs-down, here are the reasons why I refuse to give up on at least one family vacation each summer.

1. New experiences bond people. The same old routine is comfortable, yes. But experiencing new, exciting and maybe slightly uncomfortable things together bonds a family. You share a moment and an emotion and are closer because of it.

2. New places breed learning. Our kids read about places in school but there is something so much more tangible and magical about actually seeing these places. Hiking up to Delicate Arch is going to stick in their memory better than seeing a picture. Traveling to Civil War sites makes history come alive, especially if youre like my parents who always made us charge across the battlefields in a mini re-enactment. And nothing can teach kids about the simultaneous vastness and oneness of the earth like standing on the shore of an ocean, feet sinking into the sand and salty air whipping through their hair.

3. New people foster empathy. We want our children to develop empathy for people who have different backgrounds and life experiences, but thats pretty difficult to do unless you actually meet these people and appreciate their way of life. This could be anything from visiting a different country to even just seeing a different type of neighborhood. The more we expose our kids to different types of people, the less different they seem.

So, yes, when we get home from our vacation this summer, we will be a little poorer. We may be nursing sunburns, and we may be shaking sand out of our suitcases for months.

But well also be bringing home memories, renewed relationships, tall tales and views of the world you can only get by venturing out into it.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
